So as I'm building, flying and maintaining quads, I'm needing replacement parts (screws, nuts, silicone grommets, etc) for the one's that come in the frame kits. As I've looked around, quality and content varies in these kits on Amazon and other websites. I'm looking for kits that have the best content of "needed components." Like a good assortment of different sized M3 screws, plus nuts, plus vibration isolaters (for FCs), etc. I can find no shortage of these things to buy, the I'm mostly finding kits that are incomplete (only screws, etc), contain just a few individual parts, or are of poor quality. Thanks in advance.
